Making Modified Cases, SEB Rest Upgrades, ChargeMaster Tuning

Erik Cortina Video SEB Rest NEO Upgrade coaxial Lambang Modified Case Hornady Length gauge RCBS Chargemaster

Erik Cortina is one of the nation’s top F-Class shooters. A member of Team Lapua-Brux-Borden, Erik has been a top performer at National and World F-Class Championships. Erik is also a very smart guy and a skilled toolsmith who has upgraded his shooting equipment in interesting ways. Today we feature three “How-To” videos from Erik. These show how to upgrade a SEB Coaxial Rest, how to improve the performance of an RCBS Chargemaster, and how to create your own Modified Case for measuring length to lands. Watch and learn…

1. How to Make a Modified Case for the Hornady OAL Tool

Hornady Stony Point Tool OAL O.A.L. gauge bullet seating length ogive checker

In this video, Forum member Erik Cortina shows how to create a custom modified case for use with the Hornady Lock-N-Load Overall Length Gauge (formerly the Stoney Point Tool). While Hornady sells modified cases for many standard cartridges, if you shoot a wildcat such as the 6mm Dasher or .284 Shehane, you’ll need to create a custom modified case. And even if you shoot a standard cartridge such as the .308 Win, you can get more consistent measurements if you make a custom modified case from a piece of brass fired in your chamber.

MORE INFORMATION: Want to learn more? We published a much longer story in which Erik explains in greater detail how to made the Modified Case. That article illustrates the 5/16″ – 36 RH HSS Tap required and shows how to set up the lathe to drill and tap your case. If you are serious about making your own Modified Cases, you should Read the Full Article.

2. How to Upgrade your SEB Co-Axial Joystick Rest

Erik Cortina Joystick SEB Rest accessory f-class feet holder

Joystick (coaxial) rests are used by top shooters in benchrest and F-Open disciplines. With coaxial rests, you can adjust both vertical and horizontal aim instantly in one fluid movement — there are no mariner wheels to spin or knobs to turn. Just gently stir the joystick to move up, down, or sideways. Erik Cortina explains: “If you want to get into F-Class (Open) and want to win, you should get a SEB rest. SEB makes an excellent product, but the one thing we upgrade automatically … is adding the F-Class feet. These have a bigger footprint and a spike on the bottom [so you can] dig the feet into the ground and make your rest a lot more stable.” In this video Erik installs a set of Blake Machine Co. F-Class feet. These feature a set-screw, so they are easy to attach and then remove for travel (no Loctite!). “Simple yet effective” declares Erik.

In the second half of the video (starting at 5:30), Erik installs a Dan Bramley Joystick Holder. This features two clamp-on cradles that hold the joystick crosswise below the top (see photo). This handy accessory ensures your handle always remains with the rest (and doesn’t get left at home when you travel to a big match). This joystick holder has been popular with competitors. Erik says, “The Bramley Joystick holder is $60.00 — money well spent.” To order, email Dan at dbramley [at] yahoo.com.

3. How to Make the RCBS ChargeMaster 1500 Work Better

Erik Cortina has been fiddling around with his RCBS ChargeMaster and he discovered something interesting. Through a series of tests he determined that the ChargeMaster dispensed slightly more precise charges when he trickled the last few 10ths of a grain on to the RCBS pan. Erik wasn’t expecting this result, but he confirmed there may be a slight benefit to this trickling method (as opposed to allowing the ChargeMaster to dispense the full charge). You can see Erik’s test procedure in this video:

We should note that Erik’s preferred method of weighing powder is to first dispense a slightly lower charge with the RCBS, transfer the pan to a laboratory-class Sartorius magnetic force restoration scale, then trickle up with his Omega (Dandy Products) Powder Trickler. However, if you don’t have a $800+ laboratory-grade scale, you might just try trickling on to the ChargeMaster pan.

MORE INFORMATION: We have published a more lengthy Bulletin Article that covers Erik’s Chargemaster Performance Findings in greater detail. That article has more photos plus a clever, bonus “Beep Defeat Tip”. If you own a Chargemaster, we recommend you READ the Full Article.

Wow Factor: Seb’s Wood and Aluminum F-Class Stock

We first featured this amazing stock last year. We felt this creation was such a stunning piece of work that it deserved a second look. If you missed this masterpiece the first time around, feast your eyes…

Sebastian (“Seb”) Lambang, creator of the SEB Coaxial Rests and the Coaxial Joystick Bipod, has engineered an impressive new wood and aluminum F-Class stock. The stock features a long, box-section aluminum fore-end with a wood rear section and wood-trimmed “wings” on the front bag-rider. The aluminum fore-arm has “buick vents” for weight reduction. From the end of the action rearward, the stock is mostly wood, with light and dark fancy wood laminates on opposite sides (left and right).

Accurateshooter.com Seb Lambang F-Class wood aluminum stock bag rider

The foot of the buttstock has a very wide aluminum rear bag-rider with rails. The rear wood section appears to be two solid pieces of wood — but that is deceiving. Seb explains: “To save weight, the buttstock is hollow (using thin-walled wood)”. To strengthen the construction, Seb added carbon fiber inside the buttstock. So what you see is a wood outer shell with carbon fiber layers on the inside. The stock sports vertically-adjustable cheek-piece and buttplate. The thick, rubber buttpad should diminish felt recoil even when shooting big cartridges with heavy bullets.

This is an interesting, innovative stock design. And as with everything Seb produces, the craftsmanship, fit and finish are superb. We may get a chance to see how well this new stock shoots at the F-Class World Championships later this month in Raton, New Mexico.

Seb also crafted a handsome set of angled scope rails with beautifully-machined scope rings. Imagine being able to custom-make one-off products of this quality in your own machine shop!

SEB NEO Front Rest — Unique Features of This Co-Axial Design

SEB Neo front coaxial rest

Our friend Sebastian (“Seb”) Lambang recently released some photos that illustrate the “inner workings” of his advanced SEB NEO Front Rest. If you’ve ever wondered how a joystick front rest works, and how the parts go together, study the photos below. In addition, for those who use a NEO rest in competition, Benchrest Champion Mike Ratigan offers some PRO USER Tips that will help you get the best results from your NEO.

SEB Neo front coaxial rest

Unique Features of the SEB NEO Front Rest:

  • Lots of Travel — 43 MOA Vertical and 48 MOA Horizontal via joystick alone. The NEO offers more joystick travel than any other coaxial rest.
  • Variable Joystick Movement — The NEO is the only rest that can be configured for reverse action mode. That means you can optionally set it to lower the rifle with an up movement of the joystick if you prefer. (Standard setting raises rifle with up joystick movement.)
  • Rack & Pinion Risers — The NEO has dual support columns with Rack & Pinion system, offering a very broad vertical adjustment range.
  • Optional Counter-Weights — The NEO comes standard with a spring-loaded top mechanism to help hold up the rifle. Optional counter-weights allow you to reduce spring “pre-load”. Many people feel the counter-weights also allow a smoother, less jerky movement.
  • Reversible Base — The NEO’s base can be set-up with either the long leg in the rear or the long leg in the front. Putting the long leg in front gives more room under the rifle.
  • NEO Packs Flat — The SEB NEO is easily dismantled for transport, and can pack nearly flat. This is a big advantage when traveling.

CLICK HERE for Complete SEB NEO Coaxial Rest Instructions (PDF File)

SEB NEO PRO TIPS from Mike Ratigan:

Counter-weight Function and Calibration: “With the Seb NEO, equipped with the optional static counter-weight, the shooter can calibrate the counter weight to the rifle weight. The counter-weight is used to hold up the rifle. Clamping pressure of the sliding plates is NOT used to hold up the rifle like other coaxial rests on the market today. Other coaxial rests apply enough clamping force to the rest top mechanism sliding plates to resist the downward movement of the top when the rifle weight sets on the rest. This one feature of the Seb NEO almost completely eliminates bullets falling out of the bottom of your groups because the rest moved (or falls) down when you fired the rifle. This function is very important.”

SEB Neo front coaxial rest

On Hand Position: “I try to keep the palm of my hand grounded to the bench at all times. To do this at the closer distances, the handle will be laying flat (bend to the side) while shooting on the bottom of the target. To move to the top up (for right-handed shooters) I rotate the handle counter clockwise, which [raises the top] while maintaining my palm grounded to the bench.”

On Front Bag Fill: “Give some coarse sand blasting sand a try with the small stuff screened out. This will help reduce compaction from daily use.”

SEB Spreads the Joy — Gen II Joystick Bipods Arrive in USA

Sebastian Lambang Joy-Pod F-TR bipod

It was Christmas in April this weekend, as our new GEN II Joystick Bipod system arrived — thanks to Sebastian (Seb) Lambang of SEB Coaxial. We’re anxious to try this sophisticated new system on a variety of rifles, both small-bore and big-bore. Designed for F-TR shooters, we think the new Joystick bipod (aka “Joy-Pod”) may also prove popular with tactical shooters and varmint hunters who need a lightweight, yet easily-adjustable front support. Like his coaxial front rests, Lambang’s Joystick Bipod controls both horizontal (windage) and vertical (elevation) with a single control arm. In addition, the GEN II “Joy-Pod” offers cant adjustment with its tilting head.

Sebastian Lambang Joy-Pod F-TR bipod

Gross height can be easily adjusted on the vertical legs, both of which feature a column of precision-machined teeth (like on a jack), with a positive quick-adjust locking mechanism. The whole Joy-Pod system weighs about 21 ounces, and SEB even provides a handy nylon storage case.

Sebastian Lambang Joy-Pod F-TR bipod

We’ll be field-testing our new Joy-Pod in the near future and we’ll let you know how it works. SEB is not soliciting advance orders just yet — as there may be some final mods on the production version. Price hasn’t been set yet, but it should be competitive with the popular F-TR wide-base bipods on the market. If you’re intrigued, you’ll find many more hi-rez product photos on Seb Lambang’s Facebook Page.

Seb Unveils Lighter Yet Stronger GEN 2 Joystick Bipod

Seb Lambang of SEB Coaxial has revealed the GEN 2 version of his revolutionary joystick bipod (aka “Joy-Pod”). The latest version is lighter yet more rigid. The GEN 2 design features a longer handle plus built-in cant adjustment. Seb’s first-generation Joy-Pod was tested last year in Great Britain. Laurie Holland has been testing a modified version of the GEN 1 design, and he reports that it is working great.

Seb Lambang Sebcoax joystick coaxial bipod

Seb Lambang Sebcoax joystick coaxial bipodThe GEN 2 design incorporates lessons learned with the first prototype. It offers more reach and less weight. A clamp on each leg allows for easy coarse height adjustment.

Importantly, the head unit now allows +/- 14° of cant adjustment. This allows the shooter to fine-tune the cant of his rifle to suit the terrain, or his preferred rifle orientation. Currently cant is adjusted with a screw on the Joy-Pod head unit, but the production version will adjust cant via a handy locking lever.

Lighter Yet Stronger Design
Seb tells us: “The GEN 2 design weighs just 20.6 ounces (584 grams) — very light for a joystick bipod — yet the new design is more rigid than my first prototype. This new design can accept about 50 pounds of weight with almost no flex.”

Seb Lambang Sebcoax joystick coaxial bipod

Seb has experimented with a variety of bipod configurations, including an offset design (shown below) with asymmetrical arms. One horizontal arm is longer than the other. This moves the rifle’s mass to one side (so it is not centered between the two feet). The goal of the offset design is to counter torque and rocking when the gun is fired. Will the offset design work? No one really knows yet.

Seb Lambang Sebcoax joystick coaxial bipod

Seb plans to offer a variety of feet/sled options — including round bases, plastic runners, and aluminum cone-style bases with spikes. In addition, at our request, Seb may experiment with large, cylindrical style feet, like those used on the Jennings chassis with integral bipod.

Seb’s joystick bipod is still in the prototype stage, so no price has been set yet. However, Seb hopes to have production versions available before the end of 2013. Perhaps a few pre-production units may be ready in time for the F-Class Worlds in Raton, NM in August.

SEB MAX Coaxial Front Rest — Field Test by Sam Hall

[haiku url=”http://accurateshooter.net/Video/samhallmax.mp3″]Click PLAY to hear Sam TALK about SEB MAX
coaxial joystick rest.

“It’s a keeper” — that’s what Sam Hall, 4-time IBS 600-yard Shooter of the Year, told us after he test-drove the new SEB MAX coaxial front rest. Over the past two months, Sam has been testing the new SEB MAX with his competition benchrest rifles, with a variety of forearm widths from three inches to eight inches, and weights from 17 to 61 pounds.

Did Sam like the SEB MAX? He did indeed — in fact he was so impressed with the MAX rest that he is selling his current front rest and he will be using the SEB MAX for both LG and HG matches.

SEB Coaxial MAX Rest Sam Hall

In designing the SEB MAX rest, Sebastian (“Seb”) Lambang set out to build a rest that would handle true heavy guns up to 45kg and also adapt to lighter rifles with a variety of forearm widths. This was quite a challenge, but he pulled it off. The SEB MAX quickly adapts to fit narrow, medium, and wide forearms, with a simple adjustment of the side plates on the three-piece front bag. You can change from 3″ to 5″ to 8″ width in seconds. If you prefer a conventional one-piece front sand-bag, SEB offers one-piece bags sized to fit various forearm widths from 2.5″ to 8″.

SEB Coaxial MAX Rest Sam Hall

The SEB MAX also adapts to different rifle weights through the use of a front counter-weight for the heavy big boomers. With a standard 17-lb Light Gun, you can run the MAX with no counterweight. The joystick control movement is very smooth and with the internal springs tuned right, you can shoot with your hand off the joystick. When you want to switch to a true Heavy Gun, simply attach the counterweight arm to the front of the gun. SEB can supply custom counter-weight “donuts” tuned to your specific Heavy Gun. Sam Hall reviews the features of the SEB MAX in the video below.

Watch SEB MAX Video Review (Part 1 — Light Gun)

Does the SEB MAX retain its smooth movement even with a true Heavy Gun on the front bags? Absolutely. Sam reports that “When shooting my 61-pounder, with the counter-weight in place, the joystick movement is smooth and predictable — it feels just like the Light Gun”.

To prove how well the counter-balancer works with a true Heavy Gun, Sam put his 61-lb Maxi-Tracker on the SEB MAX, attached the appropriate counterweight, and then shot a group at 600 yards without touching the joystick during a four-shot string. To Sam’s amazement, the gun produced a 4-shot group under 1.5″. Sam says: “That was in mid-day with some mirage. That’s about the best this gun can do in those conditions. It was impressive to be able to run a string with a 61-pounder and not touch the joystick.” You can see this in the Part 2 Video below.

Watch SEB MAX Video Review (Part 2 — Heavy Gun)

Superior Build Quality, Unique Versatility, and Outstanding Performance
Sam had high praise for the workmanship, fit, and finish of the SEB MAX: “This rest is a work of art. I’m not easily impressed by most products, but this is one fine machine.” Sam added that the SEB MAX is not just pretty — everything functions very well: “The sideplates have quick-release handles so you can change widths quickly. The course elevation control is very smooth and easy to use. With the course elevation locked, there is plenty of vertical travel (elevation) and plenty of side-to-side travel with just the joystick.” Sam was also impressed with how well the 61-pounder tracked on the SEB MAX: “I’ve been playing with it… and the gun seems to track perfect.”

Sam also praised the micro-fiber fabric SEB uses for both the three-piece and conventional one-piece front bags: “This micro-fiber is great. You don’t need to use any silicon or powder or anything to slick it up, yet the forearm slides on it better than anything I’ve ever seen.”

Sam likes the modular construction of the SEB MAX. Sam found that, when he was just shooting a Light Gun, he could remove the rear foot, making the rest easier to move around. Like the SEB NEO rest, the MAX rest breaks down into flat modules so it packs more compactly for shipping.

SEB MAX rests are currently in the final stages of production. Price for the USA market has not yet been set. You can get on the pre-order waiting list by contacting Ernie Bishop in Gillette, Wyoming. Call (307) 257-7431, or email ernieemily [at] yahoo.com. For other markets consult dealer list on www.SebCoax.com.

Weight: The MAX weighs approximately 18.4 kg (40.5 lbs) without the counter-weight, with bags empty. Sam’s rest with full bags and counter-weight is about 45 pounds.

Rest Size: Side to side footprint (center to center of leveling screws) is approximately 13.78″. Dimension from back to front is about 14.17″.

Seb Does Diggle… and Bisley and London

Our friend Sebastian Lambang, creator of the SEB Coaxial rests and the new SEB Joystick Bipod, recently visited Great Britain to participate in the European F-Class Championships. While in the UK, Seb visited the famous (infamous?) Diggle Range, as well as London Towne. Seb was hosted by Brit shooters Brian Fox and our buddy Vince Bottomley (who writes for the TargetShooter Magazine).

Shooting in the UK
Report by Sebastian Lambang
After flying from Surabaya to Manchester airport, Brian Fox picked up my wife Lily and me on Oct. 26 morning. We then went straight to Diggle Hotel. Saturday I shot the 800-yard match at Diggle Range and Sunday I shot the 300m ‘Tactical’ Match.

Monday to Wednesday morning Lily and I did sight-seeing in London. Then we went to Bisley by train. I got a little practice time on Thursday then shot the individual match on Friday and Saturday. The team match was on Sunday but I didn’t shoot it since a friend took us to his house.

Bisley Was Cold and Conditions Were Hard to Read
I think I didn’t do very well in the Europeans. Probably because this was my first-ever F-class match, and the temps were too low for me. I was told also that Bisley is hard to shoot, the wind flags pointing ‘everywhere’, and I wasn’t sure what I should I watch to judge the conditions. I can’t trust the wind-flags, I couldn’t see mirage most of the time to help to determine the hold off. However I really liked the Championship event and enjoyed the shooting. Congrats to Lee Tomlinson (F-Open Winner, 459.30), Tim Stewart (F-TR Winner, 439.23) and Great Britain’s victorious F-Open and F-TR teams.

Vince Bottomley supplied a rifle for me to use at the Championships. Vince is a great guy indeed, he helped me with the rifle, the loads etc., and most of all he spent three full days with me while I was shooting the match. I can’t thank him enough.

Testing the New SEB Joystick Bipod

AccurateShooter: How did the new Joystick Bipod Work?

Seb: Unfortunately I didn’t have much time to try the bipod myself. But Thursday afternoon several Spanish shooters tried the bipod on their gun and they said that the bipod works fine and their shots went into the spot they want. I tried a few rounds with their gun but the impacts were not as expected … probably because I shot their F-TR .308 gun free recoil. [Editor: Even with ski-type bipod feet, you will usually benefit by having a pretty firm grip on the gun — not a death hold — but contact with the gun at multiple points.]

AccurateShooter: When will the bipod go on sale? Is the design finalized?

SEB joystick bipodSeb: I still need to perfect the legs of the bipod, I think. I will probably make two models, one with compactness in mind and one other with the lightest legs possible. The MAX rest is in production currently, and then I’ll make another 200 NEO rests for the people on the waiting list. After that we could probably start bipod production. I do hope that the bipod can be ready for sale sometime in mid-2013. The first batch would be 100 units. If my prediction is correct, all 100 units will be sold or spoken for.

AccurateShooter: How much will the production version of the Joystick Bipod cost?

Seb: Still not sure, but it should be around $350-$400 in the USA. The most expensive part is the coaxial unit. According to Brian Fox, the bipod attracted a lot of attention/interest during the match and if I had a dozen units with me, we might have sold them all at the match.

Great Visit to the UK
I really enjoyed my visit to the UK, especially visiting with Brian Fox (he is a great guy and genuine indeed!) and meeting fellow shooters from other European countries. I learned a bit from the F-class shoot and I think the bug has bitten me. It’s also nice to see a sea of SEB rests at the Bisley range in the F-Open Class.

I send my thanks to all the people I met during my visit. It is great to make new friends, and I’m happy to be a part of this great group of shooters.

World’s First Joystick-Controlled Bipod — NEW from SEB Coaxial

Sebastian Lambang SEB coaxialSebastian (Seb) Lambang of SEB Coaxial, a brilliant designer and fabricator, has created an ingenious joystick bipod. The first coaxial bipod we’ve ever seen, Seb’s new bipod is a superb example of creative design and smart engineering. This unit gives F-TR and other bipod shooters precise, one-handed control of both windage and elevation. Seb’s innovative joystick bipod is yet one more example of the innovative, advanced engineering we’ve come to expect from his company. We think this guy could be building Formula 1 cars if he set his mind to it. We are fortunate that Seb loves shooting, so he applies his talent to designing and building great new products for the shooting sports.

Seb tells us: “I just finished a prototype joystick bipod, i.e. a bipod with joystick (coaxial) elevation and windage control. This patent-pending bipod is my newest project/invention. As far as I know, there is no one that makes this type of bipod… so it’s probably the only one in the world.” We already know some shooters who want to order Seb’s joystick bipod, but Seb cautions: “It’s not for sale yet. It’s still in prototype step. There is always a rough draft before the masterpiece.”

Sebastian Lambang SEB coaxial

Seb will test and refine the design in the next couple of months before production starts. But Seb is quite satisfied with the design so far: “The rigidity, ease and comfort of use, and compactness, are already OK in my opinion.” Folks in Europe will be able to see the design very soon. The first real-world test of Seb’s new joystick bipod will be at the European F-Class Championship, slated for November 2-3 in the UK. Seb notes: “I won’t be shooting F-TR in the match, but I will ask some fellow F-TR shooters at the Bisley range to test it, and provide feedback.” Seb invites Daily Bulletin readers to look at the photos and provide comments or suggestions on design enhancements.

Technical Description
Sebastian Lambang SEB coaxialAt the lowest setting with the adjustable legs, the SEB bipod is approximately 6″ tall. At the highest setting, the unit is about 9″ tall. To smooth upward movement of the rifle, Seb designed the coaxial head with “built-in uplift”. The joystick itself is about 10″ long, with a collet-type head. When folded, the new SEB Bipod is relatively compact, about 9″ long x 5″ wide x 2″ thick. Most parts are made from aircraft grade 7000 series aluminum. The current weight of the prototype is 26 ounces (740 grams). Seb is working on reducing weight for the production models.

Joystick Function and Adjustment Range
As with SEB Coaxial front rests, the joystick function is user-selectable. The joystick handle can operate either ‘up for up’ or ‘up for down’, simply by reversing the unit and the joystick. The bipod’s effective windage and elevation range* is approximately 38 MOA horizontal (windage) and 16 MOA vertical (elevation). Seb explains: “That’s not as much as my other rests, but for F-Class use it should be adequate. The finer the adjustment, the better on the target and the smoother the joystick operation. It’s like using a scope with 1/8 MOA adjustment rather than 1/4 MOA.”


*True vertical travel is about 32 MOA but in the field the rifle stock will limit how far you can lift the joysticK. Note also that the adjustment range varies with your set-up geometry. The shorter the distance between the rear bag and the bipod, the greater the travel in MOA. This means that if you extend the distance between rear bag and bipod, you will lose some MOA travel.

New Ultra-Wide SEB MAX Front Joystick Rest Revealed

Sebastian Lambang, creator of the original SEB Coaxial Rest and the SEB NEO Rest, has a new product in the works. Seb has modified and upgraded his superb NEO rest, so that it can handle heavy, long-range benchrest rifles with ultra-wide forearms. Seb calls his super-sized front rest the SEB “MAX”. As you can see in the photo below, the MAX looks like a NEO but with a wider stance and more substantial rest top. Spring rates are optimized to handle rifle weights up to 45kg (99 pounds), using appropriate counterweights. Seb hopes to complete production of fifty (50) SEB MAX rests by late August 2012.

SEB Max front rest

MAX Rests Use Counter-Weights to Handle Very Heavy Rifles
When configured for use with true Heavy Guns, SEB MAX rests will be supplied with adjustable counter-balance weights in load-specific sizes. For example, a 1.8-lb counter-weight is used for a 40-lb gun, a 2.3-lb counter-weight is used for a a 60-lb gun, while a 2.6-lb counter-weight is fitted for a 70-lb gun. The basic counter-weight can be augmented with additional steel sections. Seb tells us: “The basic ‘default’ counter-weight is a 1″-diameter shaft, about 7″ long. Additional 2.5″-diameter SS ‘rings’ can be fitted on the main shaft to balance the action. When people order the MAX, they must provide the weight of their gun. I will then craft the appropriate ‘rings’ in various sizes to properly balance the weight of the customer’s particular gun and thereby make the action smooth to operate.”

Watch SEB MAX Prototype Used by Stuart Elliot
In this video, Aussie Stuart Elliot uses a prototype SEB MAX with his .300 Win Mag Heavy Gun at a 1K benchrest match in Brisbane, Australia. Stuart, who runs BRT Shooters Supply, recently won the Australian 500m Fly Shoot Nationals shooting a .300 Win Mag.

New SEB MAX Rest Based on Successful NEO Rest Design
Below is the standard SEB NEO rest. The MAX is wider and will hold a rig up to 45kg. The MAX represents an evolution of the original NEO design. As anyone who has had the pleasure of using one knows, the NEO is very smooth to operate and has a huge range of vertical and horizontal travel. In addition, the NEO can be quickly dis-assembled to store flat. The new SEB MAX can likewise be dis-assembled for easier storage and transport. Photo by R.J.Hamilton.

Seb’s Wild 6 PPC + .284 Win Fat-Bottom Hammerhead Convertible

You interested in a really wild, innovative bench gun that can shoot both short-range and long-range matches? Check out Seb Lambang’s latest “do-it-all” rifle. It’s a switch-barrel rifle combining two very different chamberings: 6 PPC and .284 Winchester. With that caliber combo, Seb’s covered from 100 yards (LV/HV mode) all the way out to 1000 (LR Light Gun mode). But the dual chambering is not the rifle’s only trick feature. Exploiting the new long-range benchrest rules, Seb has fitted a 3″-wide, flat rear metal keel to the buttstock. That counter-balances his 30″-long 7mm barrel, improves tracking, and adds stability. Seb built the stock and smithing was done by Australian gunsmith David Kerr.

Seb Lambang 6PPC .284 Win Benchrest hammerhead

Detachable Hammerhead Wing Section Plus Fat-Bottom Keel
To further reduce torque and improve tracking, the stock features an 8″-wide, detachable fore-end fixture. This “hammerhead” fore-end section has extended “wings” on both sides, making the rifle super-stable. The hammerhead unit can be removed, leaving the stock 3″ wide for use in registered benchrest matches where 3″ is the maximum width. The photos below show Seb’s gun in .284 Win Long-Range (LR) Light Gun mode.

Seb Lambang 6PPC .284 Win Benchrest hammerhead

Yes This Rig Shoots … In Both Configurations, Long-Range and Short
Seb has already used his switch-caliber, switch-barrel rig successfully in competition. Seb tells us: “The gun shot and tracked real well either in 6 PPC LV/HV mode or in .284 Win LG mode. I love it! With this gun I placed Top 10 for the Two-Gun at the Harry Madden Championship in Brisbane, Australia just a few days ago and took the silver medal for the 500m Flyshoot with the .284 Win on the next day. So who says a switch-barrel rifle can’t (or doesn’t) work?” And get this, Seb finished the stock just four days before the Brisbane match. He glued-in the action the evening before the match and shot it the next day in competition. Pretty impressive we’d say….

Sebastian Lambang Hammerhead 6PPC

Seb Lambang — Indonesian Innovator
If you don’t know already, Seb Lambang is the designer/builder of the innovative SEB Coaxial rests. These are some of the best joystick rests on the market. The latest version, the SEB Neo Rest, is a brilliant design that folds flat for transport, yet offers extended vertical and horizontal travel and a rest top that can adjust from roughly 2″ wide to over 6″ in width. This Editor uses a SEB Neo for both bench and F-Class shooting and it is my favorite joystick rest. Rest in photos is a SEB Neo MAX.
